Abstract: In the present report a method is introduced by which it has become possible to analyze data for irradiation induced changes in graphite utilizing mathe-matical-physical aids. The analysis was performed with more, than thirty graphite grades for four property changes and both directions of anisotropy. As a result, smooth data sets completed by means of interpolation and extrapolation methods are presented in both graphical and mathematical-functional ways. The graphite data cover irradiation temperatures ranging between 300° C and 1400° C and irradiation doses up to approximately the limits of sercice life. Statistical errors due to experimental uncertainties are also determined as a function of dose and temperature. The semi-empirical damage model employed for the analysis is derived fromphysical principles. It is explained in detail and its limits and potential for further use are discussed. The understanding of radiation damage in graphite has been augmented. The theoretical basis for the model is provided by the well-known concept of equivalent temperatures and a comparison is made with the theory of B. T. Kelly.
